6-chloro-N-[2-(4-methoxyphenyl)ethyl]pyridazin-3-amine

6-chloro-N-[2-(4-methoxyphenyl)ethyl]pyridazin-3-amine is identified by CAS 1040013-91-9 and molecular formula C13H14ClN3O. PubChem resolves the CAS to a single compound, CID 29541192, with molecular weight 263.72. The verified connectivity is SMILES COC1=CC=C(C=C1)CCNC2=NN=C(C=C2)Cl, and InChIKey ZYNRTXKSPZFJAX-UHFFFAOYSA-N denotes the same molecular graph. It is one neutral component.

The pyridazine ring contains two adjacent nitrogens, chlorine at position 6, and an amino substituent at position 3. That amino nitrogen is bonded to a two-carbon ethyl chain terminating at a phenyl ring. Methoxy lies para to the ethyl attachment on this phenyl group. The third nitrogen is the linking amine, and the single oxygen belongs to methoxy. The two-carbon spacer is explicit in both the name and SMILES; a direct anilino connection would be a different graph even if a shortened label appeared similar.

For a structure-defined inquiry to Rlavie, provide the full N-substituted name, CAS 1040013-91-9, and the requested quantity. Include a MOL or SDF structure file so the 6-chloro/3-amino pyridazine pattern, two-carbon linker, and para-methoxyphenyl endpoint can be reconciled with PubChem CID 29541192, the stated SMILES, and InChIKey ZYNRTXKSPZFJAX-UHFFFAOYSA-N. That comparison should be completed before request-specific details are evaluated. Formula C13H14ClN3O establishes elemental composition but does not show linker length or ring locants, which are necessary to keep this record distinct.
